OIL-BURNER.

To all whom it may concern:

Be it known that I, ALEXANDER O. TESCH, a citizen of'the United States, and resident of hfilwaukee, in the county of'Milwaukee and State of Wisconsin, have invented new and useful Improvements in Oil-Burners,

v of which the following is a description, reference'being had to the accompanying drawings, which'are a part of this specification. The invention relates to heating systems. The invention designs moreparticularly circulating system in which the heat-conducting medium is heated by an oil burner.

The invention further designs to provide a thermostatically operated valve forcontrolling the amount of oil fed to the burner.

The invention further designs'to provide a heating system in which the oil in passing to the burner is vaporized by the heat of the burner.

The invention further designs to'provide in full) Fig. 2 is a plan view of the burner and vaporizer; Fig. 3 is a detail sectional view of a modified'form of jet.

The device comprises a circulating system for conducting the heating medium; a"

burner for heating said heating medium, and thermostatically operated means "for controlling'the supply of oil to the burner.

The circulating system comprises coils 4 which are connected to pipes 5 and 6' which pipes are connected to the other pipesof the circulating system, one of such pipes 7 being shown connected to the pipe 5. These coils and pipes thus form a circulating system for circulating any suitable heat-coir.

ducting medium such as steam, water or air. The oil burner comprises a burner proper 8, a plurality of oil nozzles 9 operatlvely connected together and disposed adjacent the burner 8, a plurality of coal gas nozzles 10 operatively connected together'anddisposed adjacent the burner 8, a vaporizing Specification of Letters Patent.

coil connected'to said oil-nozzles, an oil I screw plugs 20 which may be readily removed, when it is desired, to clean the burner pipes; Inclined branch pipes 21 communicate with each of the burner pipes 14:. V

The oil nozzles'9 are operatively connected togetherf'by' a common connecting pipe'22 whichis provided with a plurality PatentedMfay 18, 191 5. Application filed January 15,1915. seiiaimfafna V of side eXtensions'23 having threaded apertures 24 therein. y

In the construction shown in Figs. 1 and 2 each nozzle consists ofa member having its end 26 in threaded engagement with one of the apertures 24 in the pipe 22 and each nozzle is provided with the usual form of pet-cock valve 27.. v

In the modified form shown in Fig. 3, the nozzles 25 are integral with the connecting pipe '22""and extend outwardly on either side thereof. The ends of the nozzles 25 have'conical seats 28 adjacent an opening 29." In place of the pet-cock valve in the other construction'I "provide valve rods 30.

foreach ofthenozzles which have a pointed end '31 slidable within the nozzle opening 29 and aconical portion 32 adjacent the end 30 which is adapted to be'moved against the valve seat 28 to close the nozzle opening.

Each rod 30 has a threaded intermediate portion 33 engaging a threaded aperture 34 in the extension 23 on the pipe 22 and each extension has, a recessed end35 for re-.

ceiving a packing ring 36 mounted on the I rod 30 andheld in place by a cap nut in threaded engagement with said extension.

The'end's' 38 of the rods 30 are bent, down to forrnoperating handles. The rods 30 not only serve as valve rods, but also by'reason of their pointed ends 31 serve as cleaners for the nozzles.

The gas nozzles 10 are operatively connected together by a common connecting pipe 39, similar to the pipe 22, which pipe is provided with a plurality of side extensions having threaded apertures 41 therein similar to the extensions 23. The gas nozzles are similar to the oil nozzles 9 and are similarly connected to the pipe 39. and each is provided with a pet-cock 42. The pipe 39 is connected to the gas main (not shown). The gas from these nozzles is ig: nited and used to initially heat the burner 8 and the vaporizing coil 11.

The vaporizing coil 11 consists of a plurality of turns ofpipe 43 which is connected at one end 44 to the oil-nozzle pipe 22 or 22 and is provided with a valve 45; This coil is disposed above the burner. so that the heat passing therefrom will heat the oil and cause it to vaporize, in which condition it issues from the oil nozzles. The vaporizing. coil 11 is connected at its other end 46 to the inlet valve 12 through aperture screW plug 47. i i

The inlet valve 12 comprises a valve casing 48 having a valve chamber 48 therein, and an apertured valve block 49 slidably and adjustably mounted in said casing adj cent the oil inlet 13 and a valve rod 50. The valve block 49 is provided with a valve seat 51 therein adjacent its aperture and a recess 52 in its top. The means for adjusting the position of the valve block 49 comprises a cam 53 mounted the recess 52 and carried by an operating rod 54 which is rotatably mounted in an apertured screw plug 5. having a recess 56 therein for receiving a packing ring 57 mounted on said rod and held in place by an apertured cap nut 58. Resultantly the rotation of the rod 54 will rotate the cam 53 which, engaging with the sides of the recess 52 in the valve block, will move said block within the casing. The valve rod 50 is slidably mounted in the casing 48, a packing ring 59 being mounted therein and held in place by a cap nut 60. This valve rod 50 has a head 61 adapted to register with the valve seat 51 the block.

The means for thermostatically controlling the supply ofoil to the burner comprises thermostatically operated means for controlling the operation of the valve rod 50, said means consisting of a strip of zinc 62 connected to a strip of tin 63, both of said strips being disposed within the pipe 7 and connected at their ends to said pipe by bolts 64 and spaced away from the inner sides of the pipe by blocks 65. These two strips are connected intermediate their ends to the valve rod 50 which passes through said strips and is secured thereto by nuts 66. An opening 67 is provided in the pipe 7 adjacent the valve rod 50 for access'thereto should the parts fail to work properly and this opening is normally closed by the screw p us In operation the burner 8 is initially heated by turning on the nozzles 10 and lighting the coal gas issuing therefrom, which gas serves to initially heat the burner and the vaporizing coil 11. Vhen the vaporizing coil has been heated sufficiently to cause the vaporization of the oil within it, the valve 45 is opened and the vaporized oil passes to the nozzles 9 which are now turned on and the oil issuing therefrom is ignited by the burning gas. Now the gas nozzles are turned off and the oil, due to the heat from the burner, vaporizes itself. The burning oil heats the pipes of the circulating system and thereby heats the medium within said system. By the adjustment of the valve block 49 the space between the valve seat 51 and valve head 61 may be varied to regulate the amount of oil supplied to the burner and by the use of the thermostatic control the valve rod may be moved into or out of contact with the seat depending upon the temperature of the heating medium within thesystem. This thermostatic control operates on the principle of dissimilar expansion and contraction of dissimilar metals when subjected to different temperatures. The strip which has a greater coeflicient of expansion than the tin strip and will, on eX- panding, bend inwardly carrying the valve rod inwardly and thereby bringing the valve head 61 against the, valve seat 51 when the temperature of the system becomes too great and thus reduce or stop. the feed of the oil until the temperature drops below this point and when it does drop the zinc, in contracting, moves the valve away from its seat and thus increases the flow of the oil.

Though I have shown a heating system in which the heating medium is circulated through a series of pipes which are disposed above the burner it will be obvious that the burner may be placed in the, ordinary acketed furnace to heat the heat conducting medium within the jacket.

The invention thus exemplifies a heating system in which the heating medium is heated by an oil burner which is automatically controlled by the temperature of the system.

The, invention is not to be restricted to the details of construction herein set forth but may be varied so as to be within the scope of the appended claim.

\Vhat I claim as my invention is The combination, with a heating system, of an oil burner for heating the heating medium within said system comprising a series of pipes connected together and having a plurality of burner openings therein and a plurality of inclined branch pipes communicating with said pipes, a vaporiz ing coil disposed above the burner, means for conducting the oil to the vaporizing coil, In testimony whereof, I aflix my signameans cohmprising a serie? of nozzlels 1igor inture, in presence of two Witnesses. jecting t e vaporized oi into sai urner pipes, and means comprising a series of ALEXANDER TESGH 5 nozzles for injecting coal gas into the burner Witnesses: through said inclined branch pipes to ini- LOUIS O.
